Hey guys, I just upgraded my daily driver from the fx-991ES which I had been using for a pretty long time to the fx-991CW. The UI change is pretty drastic tbh. I'm an EE student and I've got a Probability and Stats paper this semester as well. I've noticed a few thing like the Spreadsheet app and the way Distribution menu works but I wanna know the "pro" shortcuts.
I'm looking for a comprehensive guide that explains everything the fx-991CW can do and how to use it efficiently.
A few specific things I'm curious about:

1. Stats/Prob Workflow: For those doing Normal, Binomial or Poisson distributions, what's the fastest way to get your values while still matching the precision of the printed tables provided in the exams.
2. How are you guys handling Complex numbers/phasors on this? I've noticed the Variable list shows rectangular and polar form pretty cleanly, but are there shortcuts for Nodal/Mesh(Solver) I should know? In particular, solving equations with complex coefficients would be quite helpful but I can't figure out a way to do it.
3. The Spreadsheet: Is it any useful for iterative methods or lab data, or just a gimmick?
4. State Memory: I realized it keeps data in the Stats app even if you switch to the Spreadsheet app. I'm assuming this holds for all the apps. Any good ways to utilize this for multi-part problems?

These are the specific questions I wanted to ask, but a comprehensive guide would be much appreciated.

Hi everyone, not sure if this is the right place to ask, but I’m an EE undergrad. My university mainly focuses on power, so we don’t have a Signals and Systems course (or at least I think that’s why).

Does anyone know of an online course that offers a certificate or some kind of proof of completion? I need something to show that I’ve actually taken the course. Also, I do have Control this semester and Digital Signal Processing the next semester but I don't know if it's exactly the thing I need.
